Description
Technical field
The invention belongs to radioactive waste analysis and disposal technology field, be specifically related to a kind of waste liquid sampler.
Background technology
Along with the development of China's core cause, the day-to-day operation of various nuclear facilities safeguards and emergency processing constantly produces radioactive liquid waste, also has increasing old facility to face closure retired.The investigation of radioactive liquid waste source item and detection are the condition precedents of liquid waste processing, and running through nuclear facilities and close retired overall process, is also the guarantee that nuclear facilities emergency event processes safely and fast.In source item fact-finding process, sample analysis is carried out to new radioactive liquid waste that is that produce and that may exist in nuclear facilities and is absolutely necessary one and works.
At present, much face retired nuclear facilities old, do not have sampling system or original sampling system to pollute or damaged condition in facility, sampling is difficulty comparatively, and the sampling method for radioactive liquid waste when this nuclear facilities and reply nuclear emergency is generally people for direct sample.There are following 2 deficiencies in this mode, first be operation inconvenience, need personnel to come to waste tank top or melt pit personally to be fond of salty food into sampling jar sampling by the manhole on equipment or from melt pit, easily meet accident and every sub-sampling needs at least two staff to coordinate carry out and the running time longer.Next is that personnel must stop in the stronger region of radioactivity the long period, inevitably causes the irradiation hazard to the person or other contaminations.
